Solar savings calculator
Move the sliders to estimate what solar could do for your home. It's an indicative guide — a free survey gives you exact figures for your roof.
Your details
A battery lets you use more of your own solar instead of exporting it cheaply.
Your estimate
Estimated install cost: £0
CO₂ avoided: 0 per year
Estimates assume an electricity price of 28p/kWh, ~900 kWh per kW per year for a south-facing roof, a 10p/kWh export rate, and self-consumption of 40% (or 80% with a battery). Your actual figures depend on your roof, shading and usage — book a free survey for a precise quote.

All package prices assume every panel fits on a single roof elevation. The price covers the cost of scaffolding to one elevation. If your roof needs scaffolding on more than one elevation, or has restricted access, that additional cost is quoted separately after survey. Prices include VAT. Domestic solar and battery storage is zero-rated for VAT until 31 March 2027. Subject to a free technical survey. We will confirm the final price in writing before any work is booked.
